Add M5Stack specific builds for esp32 light (#25550)

* Enable builds for m5stack for more apps as m5stack and devkitc are the same MCU except screen support -i.e. defaults should work * start adding some compile options for ESP32 display ... still made a TODO for actual integration * Enable m5stack in Kconfig * Things compile now * Restyle * Remove demo items * Add more config variables to get displays working * Cleanup unused widgets, add callbacks for the wifi one * Make wifi green * Cleanup device with display: no more virtual devices * Restyle * Remove unnedded log * Remove unused variable * Remove useless commment in QRCodeScreen.h * Remove one more useless coment * Update examples/lighting-app/esp32/main/Button.cpp Co-authored-by: Cliff Chung <[email protected]> * Update examples/lighting-app/esp32/main/DeviceWithDisplay.cpp Co-authored-by: Cliff Chung <[email protected]> * Update examples/lighting-app/esp32/main/Globals.cpp Co-authored-by: Cliff Chung <[email protected]> * Update examples/lighting-app/esp32/main/StatusScreen.cpp Co-authored-by: Cliff Chung <[email protected]> * Update copyright dates and remove a bunch of @file comments * Move ifdefs around * Remove useless button.h comments * Move ifdefs a bit - HAVE_DISPLAY is a result of a header --------- Co-authored-by: Andrei Litvin <[email protected]> Co-authored-by: Cliff Chung <[email protected]>
